用CCD测量激光束的光强分布

Measurement of laser beam intensity profile by CCD

本文介绍一种采用微机进行数据处理和面阵CCD作探测器的激光束光强分布的测量系统。论述了该系统设计、软件设计和误差分析。实现了对脉冲或连续激光束光强分布的实时、自动测量。

The measurement system for laser beam intensity profile using a microcomputer for data processing and a CCD detector of the two-dimensional array is introduced. The design of the whole system and the software are discussed. The error analysis is presented. A real time and automatic measurement of intensity profile of pulsed and CW laser beam has been realized.
